The type of yarn and weave structure have a high impact on fabric properties and affect on dyeing and treatment process. Double weave structure is one of the 3D Fabrics, it is more complicated than the simple weave structure. Polyester is one of the manmade yarns that have different types depending on the spinning way, the cross-section, and its tenacity. The most complete batch staining method is high-temperature dyeing. One of the most significant objectives of this work was to improve polyester fabric by adopting titanium nanoparticle size (TiO2) to provide it with multifunctional features (such as UV resistance, stain resistance, and antibacterial, self-cleaning). In general, the study was split into two sections: The first part examined the environmental benefits of using high temperatures to dye some dispersed dyes. The second part promoted the fabric's ability to perform multiple tasks after dyeing (post-dyeing with disperse dyes) by using TiO2NPs (21 nm primary particle size) in a two-step hot process that involved soaking it in a solution of TiO2NPs at 80°C before curing it at 140°C. This work aims to investigate the impact of various weave patterns and treatments on the back layer.
